By estabishing liquid systems of white rot fungi such as Phanerochaete chrysosporium, Trametes versicolor, Trametes hirsuta , Trametes hispida , the effects of several factors on the production of Manganese Peroxidase were studied. The investigation showed: ①Mn2+ was necessary for production of Manganese Peroxidase to all tested species; ②VA (0. 4 mmol/L), Tween80(0. 1%) and oxalic acid (5 mmol/L) could stimulate Manganese Peroxidase synthesis to all tested species;③to Phanerochaete chrysosporium , higher nitrogen inhibited activities of Manganese Peroxidase; to Trametes hispida , amount of nitrogen had no effect on Manganese Peroxidase synthesis; ④L-Phenylalanine (20 mmol/L), D-Phenylalanine (20 mmol/L) and Dithiothreitol (0. 1%) supressed Manganese Peroxidase synthesis; ﹖he ability of Manganese Peroxidase production by Trametes versicolor was higher than that of Phanerochaete chrysosporium, and the duration time of Manganese Peroxidase production by Trametes versicolor was longer.
